Doreen and Irena plan to leave their houses at the same time roller blade towards each other and meet for lunch after 4 hours on the road. doreen can maintain a speed of 8 miles per hour which is 80% of Irena's speed if they meet exactly as planned what is the distance between their houses?
***
8=doreen's speed
let x=Irena's speed
80%x=8
x=8/0.8=10=Irena's speed
8+10=18=speed at which Doreen and Irena's are moving toward each other
travel time*speed=distance
4*18=36
what is the distance between their houses? 36 mi
